Many applications of silicate glasses derive from their optical transparency, which gives rise to one of silicate glasses' primary uses as window panes. Glass will transmit, reflect and refract light; these qualities can be enhanced by cutting and polishing to make optical lenses, prisms, fine glassware, and optical fibers for high speed data transmission by light. Glass can be colored by adding metallic salts, and can also be painted and printed with vitreous enamels. These qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures. Because glass can be formed or molded into any shape, and also because it is a sterile product, it has been traditionally used for vessels: bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also been used for paperweights, marbles, and beads. When extruded as glass fiber and matted as glass wool in a way to trap air, it becomes a thermal insulating material, and when these glass fibers are embedded into an organic polymer plastic, they are a key structural reinforcement part of the composite material fiberglass. Some objects historically were so commonly made of silicate glass that they are simply called by the name of the material, such as drinking glasses and reading glasses.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What quality of silicate glass allows it to be used for windows?
Ah, so.. transparency

Bateman was responsible for the building of 36 new buildings for the university both on and off campus, including the expansion of the Harold B. Lee Library. He was also one of several key college leaders who brought about the creation of the Mountain West Conference, which BYU's athletics program joined — BYU previously participated in the Western Athletic Conference. A BYU satellite TV network also opened in 2000 under his leadership. Bateman was also president during the September 11th attacks in 2001. The planes crashed on a Tuesday, hours before the weekly devotional normally held at BYU. Previous plans for the devotional were altered, as Bateman led the student body in a prayer for peace. Bateman was followed by Cecil O. Samuelson in 2003. Samuelson was succeeded by Kevin J Worthen in 2014.

While no other Timely character would achieve the success of these "big three", some notable heroes—many of which continue to appear in modern-day retcon appearances and flashbacks—include the Whizzer, Miss America, the Destroyer, the original Vision, and the Angel. Timely also published one of humor cartoonist Basil Wolverton's best-known features, "Powerhouse Pepper", as well as a line of children's funny-animal comics featuring popular characters like Super Rabbit and the duo Ziggy Pig and Silly Seal.
